CHARLES G. CANFIELD, OF CLEVELAND, OHIO.

SPECIFICATION forming part of Letters Patent No. 746,789, dated December 15, 1903. Application filed October 18, 1902. Renewed June 25, 1903. Serial No. 163,121. (No model.)

. The objectof this invention is to provide a practical and inexpensive means whereby building operations, and particularly the building of walls and partitions of cement or artificial stone, may bercarried forward regardless of the weather conditions at the time;

to which ends the invention consists in a portable flexible inclosure of such construction that it may be placed around and over that portion of the building under construction,

the inclosure being preferably formed of canvas orwoven material of such nature as to transmit sufficient light and at the same time be 'water-repellant and of suflicient density as to retain heat should the building operations be carried on when the temperature is low.

The accompanying drawing is a vertical section through a portion of a building in course of erection with the improved means for inclosing the working area in position.

In said drawing the wall A, which is in course of erection, is shown as having prograssed to a point beyond one of the floors B of the building, which floors are preferably put in place as their level is reached. A skeleton framing,consisting of uprights C and riders and beams c, which latter may be and preferably are the floor-beams of the next story, is erected in advance of the wall construction, such skeleton framing constituting the support for the inclosure and is completed always in advance of the wall construction.

The. wall illustrated is of cement or artificial stone molded in situ, for which purpose The hangers E also serve to support the curtain or side wall F of the inclosure and for vas or Woven material coated or impregnated with a waterproof or water-repellant substance which will facilitate the transmission of lightas, for instance, flexible varnish or oil.

To close in the top or provide a roof for the working space, the cross-beams c are utilized as supports for flexible covers H, preferably one for each beam and sloping away on each side of the beam. The lower edges of the covers terminate in troughs-K, which may be suspended from the edges of the covers by having hooks in on the inner sides of the troughs passed through openings or eyelets in the edges of the covers, as will be readily understood from the drawing.

The drip from the troughs may be led away to any suitable discharge, or the troughs may be extended to discharge at some point beyond the building-walls where it can do no injury. I a

\Vith a structure such as described it is obvious that the building operations may be carried on regardless of the weather, as rain or snow is excluded,and, if desired, artificial heat may be supplied to warm the iuclosed area, especially if the-floors are laid as the work progresses. When it becomes necessary to raise the inclosing curtain, it may be readily accomplished by first shifting the hangers to the higher point and then attaching the mold-board-supporting ropes or other ropes running over pulleys on the hangers to the upper portion of the curtain and then hoisting the whole into its new position.

The building operations are carried on entirely from the inside of the building, and the walls as they progress incorporate the vertical portions of the skeleton frame, and thus while said frame is utilized to support the temporary inclosure it ultimately becomes a part of the building and does not increase the expense of the building nor the labor of construction, as such framing can be run in advance of the walls with the same facility that it can be run simultaneously therewith.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an inclosure for the building area during the erection of walls of buildings, the combination with the skeleton frame extending above the walls of the building, of a flexible inclosing curtain supported from said framing around the building area and means for holding the lower edge of said curtain close to the outer side of the completed portion of the wall; substantially as described.

2. In an inclosure for the building area during the erection of walls of buildings, the combination with the skeleton frame extending above the walls of the building, of hangers carried by said framing, a flexible inclosing curtain suspended therefrom around the building area and outside of the plane of the walls, and means for holding the lower edge of the curtain close to the outer side of the completed portion of the wall; substantiallyabove the walls of the building, of a flexible inclosing curtain supported from said framing around the building area outside of the plane of the walls,1neans for holding the lower edge of the curtain close to the completed portion of the walls and a sectional flexible cover for said building area with drip-troughs between the sections; substan tially as described.

4. In an inclosure for the building area during the erection of walls of buildings, the combination with the skeleton frame extending above the walls of the building, and embodying transverse beams, of a flexible surrounding curtain, a sectional cover of flexible material, each section being centrally supported on a beam and drip-troughs supported between the adjacent edges of the sections; substantially as described.

5. In an inclosure for the building area during the erection of the walls of buildings, the combination with the skeleton frame extending above the completed portions of the walls, and emboding vertical and transverse beams, of hangers on said frame extending beyond the plane of the walls, a flexible inclosing curtain suspended over said hangers, a rope for holding the lower edge of said curtain close to the completed portion of the wall, a sectional cover for said area constructed of flexible material, each section being support-
